[FFmpeg-user] Extracting sections of an MPG movie

Hi Tim, You can't cut at arbitrary points in a mpg file. Cutting can be done on I-Frames/Keyframes. In PAL-land, where I live it mostly is every 12th frame. To solve the problem, first convert the original to an all-i-frames.mpg with ffmpeg -i source -acodec copy -vcodec mpeg2video -sameq -intra all-i-frames.mpg After that you can 'start' and 'end' where ever you like.
